Description

technical field [0001] The invention belongs to the technical field of pipeline equipment, and in particular relates to a multi-applicability pipeline friction damping device. Background technique [0002] The application of pipelines is widely used in industrial production, especially in the petroleum, chemical, and energy industries. Usually, pipelines will vibrate during operation, especially high-temperature and high-pressure pipelines. Fatigue damage occurs. When the pipeline is in operation, the change of working conditions will cause periodic changes in internal pressure and flow rate, which will cause pipeline vibration, wear and loose the flanges and valves connected to the pipeline, and cause medium leakage in light cases, and in severe cases. cause serious safety hazards. Furthermore, due to the vibration of the pipeline, its welds and elbows are very easy to leak, and even cause explosions and major accidents; how to effectively reduce the damage to the pipeline...

AI Technical Summary

Problems solved by technology

In the vibration reduction of pipelines, measures such as adding rigid supports to increase the natural frequency of the relationship and setting buffer tanks, orifice plates, and damping vibration reduction technologies are often used to control the vibration of pipelines, but the vibration damping direction is generally one or several directions in the radial direction. And the axial vibration of the pipeline cannot be controlled, but in the actual piping system, the direction of the pipeline is relatively complicated, and the radial vibration of a certain pipeline will cause the axial vibration of other pipelines, but the existing technology does not reduce the radial vibration of the pipeline at the same time. and axial vibration measures
